Hi all, I am about to start and house extension and will be doubling the size of the house (it's a small house). Part of the extension will be on a subfloor with concrete posts and the other part will be on a paving slab with timber posts.
So we are adding a master br, ensuite, wir, laundry all will be on the subfloor with concrete posts, the other part will be the garage and workshop, The frame for this part of the build will be on timber posts, and then a paving slab will be poured once the footings and posts are finished.
All footings for the house extension will be a min of 150mm x 350mm, filled with concrete and then concrete/timber posts mounted.
I have questioned the engineer about the timber posts and he assures me this o.k. and what builders do! I asked if I could use concrete posts and he said the concrete slab design would have to be engineered therefore more expensive.
My concern is the life span and is this normal practice? Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅
